Parenchymal and pleural abnormalities in children with and without pulmonary embolism at MDCT pulmonary angiography.
Prior studies in adults suggest that a wedge-shaped peripheral consolidation may be predictive of pulmonary embolism (PE). In contrast, a previous study in children provided no evidence of an association between this finding and PE, but it was limited by a small sample size and was not specifically designed to answer this question. ⋯ Wedge-shaped peripheral consolidation is significantly associated with PE on CTPA studies of children. The identification of a wedge-shaped peripheral consolidation in children should alert radiologists to carefully evaluate for concurrent PE.

Fetal MRI can be performed in the second and third trimesters. During this time, the fetal brain undergoes profound structural changes. Interpretation of appropriate development might require comparison with normal age-based models. Consultation of a hard-copy atlas is limited by the inability to compare multiple ages simultaneously. ⋯ Improved interpretation of fetal brain abnormalities can be facilitated by the use of digital atlas cataloging of the normal changes throughout fetal development. Here we provide a description of the atlas and a discussion of normal fetal brain development.

Case ReportsAcute necrotizing encephalopathy in a child with H1N1 influenza infection.
Since the World Health Organization declared a global pandemic of novel influenza A H1N1 in June 2009, there has been a sustained rise in the number of cases of this strain of influenza. Although most cases are mild with complete and uneventful recovery, multiple cases of severe infection with complications including death have been reported. ⋯ To our knowledge this has not been reported in the pediatric radiology literature. We hope this case will alert radiologists to this complication and familiarize radiologists with imaging findings that herald ANE.
